چکیده

We report a systematic analysis of the relationship between salt bridge composition and 14-helix structure within a family of model beta-peptides in aqueous buffer. We find an inverse relationship between side-chain length and the extent of 14-helix structure as judged by CD. Introduction of a stabilizing salt bridge pair within a previously reported beta-peptide ligand for hDM2 led to changes in structure that were detectable by NMR.

Helix macrodipole control of beta 3 peptide 14-helix stability in water.

beta-Peptides have attracted considerable attention by virtue of their ability to populate helical secondary structures in methanol, even in the absence of stabilizing tertiary interactions. Recent efforts in beta-peptide design have produced few beta3-peptides that form stable 14-helices in water; those that do require stabilizing intramolecular salt bridges on two of three helical faces and t...

Structure-activity studies of 14-helical antimicrobial beta-peptides: probing the relationship between conformational stability and antimicrobial potency.

Antimicrobial alpha-helical alpha-peptides are part of the host-defense mechanism of multicellular organisms and could find therapeutic use against bacteria that are resistant to conventional antibiotics. Recent work from Hamuro et al. has shown that oligomers of beta-amino acids ("beta-peptides") that can adopt an amphiphilic helix defined by 14-membered ring hydrogen bonds ("14-helix") are ac...

Relationship between side chain structure and 14-helix stability of beta3-peptides in water.

Folded polymers are used in Nature for virtually every vital process. Nonnatural folded polymers, or foldamers, have the potential for similar versatility, and the design and refinement of such molecules is of considerable current interest. Here we report a complete and systematic analysis of the relationship between side chain structure and the 14-helicity of a well-studied class of foldamers,...

Molecular dynamics simulations of peptides from the central domain of smooth muscle caldesmon.

The central domain of smooth muscle caldesmon contains a highly charged region consisting of ten 13-residue repeats. Experimental evidence obtained from the intact protein and fragments thereof suggests that this entire region forms a single stretch of stable alpha-helix. We have carried out molecular dynamics simulations on peptides consisting of one, two and three repeats to examine the mecha...

Folding of a peptide corresponding to the alpha-helix in bovine pancreatic trypsin inhibitor.

A short peptide corresponding to the alpha-helical region of BPTI shows partial folding in aqueous solution (pH 7) as judged by circular dichroism (CD). Folding is temperature and denaturant sensitive, and the peptide is monomeric. The difference CD spectrum, obtained from spectra at two temperatures, indicates that the peptide folds as an alpha-helix. Difference CD spectroscopy provides a sens...
